Laravel 5.2 - Display all SQLs executed in Eloquent not working

I used to use the following code in routes.php to display all SQLs executed in Eloquent:

// Display all SQL executed in Eloquent
Event::listen('illuminate.query', function($query)
{
    var_dump($query);
});

But it doesn't work in Laravel 5.2 any more. Is it possible to get this feature back in 5.2? Thanks.
